To all whom it may concern:

Be it known that I, BERTRAM ALBERT LEVY, a citizen of Melbourne,Australia, and resident of the United States, residing at ew York, inthe county of New York and State f Iew York, have invented certain newand useful improvements in Methods of Projecting Pictures and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

lily invention relates to improvements in methods of projectingpictures; and the object of my invention is to show upon a screen aslowly-growing picture, which grows as the artist sketches it in linesof white or colored light upon a dark background.

My invention will be understood by reference to the accompanyingdrawings, in which .lligure 1 shows the simplest form of the a paratus.Fig. 2 is a front view of the screen, showin the picture it appearsthereon, and i 3 shows an improved form of the apparatus with a pictureprojected. on the screen.

itcfci'ring first to Figs. 1 and 2, a represents a s-rccn of anysuitable material, as white cotton fabric, for instance. 6 represents amagic lantern. 0 represents a slidesupport for the magic lantern,leaving the lens of said lantern entirely unobstructed, and d representsa slide having its front face covered with a black or other opaquecoating, which can be removed by any suitable means, such a pencil,brush, or stylus. The apparatus is of course to be used in a perfectlydark room and is so arranged that the screen appears perfectly black orof any other desired color when the glass slide d is in the front of themagic lantern. The artist then takes a pen, pencil, or brush and draws apicture upon the slide (1 by removing the coating in certain places. Theresult is that a picture appears on the screen greatly enlarged in linesof white or colored lightupon a dark background. The artist of coursevarice the picture as he pleases. it may represent persons, events, ormay illustrate a story which the artist tells as he sketches. heapparatus is so arranged that the screen is absolutely unobstructed, andnothing apthereon but the slowly rowing pic ture, except that in somecases the shadow of pencil is seen. This does not destroy the illusoryeffect, but rather heightens it if anything.

In the form of device shown in Fig. 3, 1 represents a lantern of anydesired construction, but preferably containing a strong electric lighthaving a lens 2. 3 represents a platemirror arranged at an angle to thelens, so as to throw the lines of light upwardly through another lens l.5 represents a slide, preferably of glass, which is provided with anopaque coating on its upper surface, which coating may be readilyremoved by a pen, brush, or stylus. It should be noted that the spaceabove the slide 5 is perfectly unobstructed, so that the artist can siton a chair in front of the table 9 on which the apparatus rests and cansketch freely upon the slide 5, moving his body and arms into anyposition he may wish. The rays of light which pass through the slide 5after a portion of the coating has been removed are received upon a lens6, which directs them upon a concave mirror 7, which throws an enlargedimage on the screen 8. The lens 6 is carried by the hanger 10 on the rodll and may be moved up or down to vary the size of the image, and themirror '7 is also pivotally mounted on the hanger l2, fastened to therod 11, and is arranged to swing in the arc of a circle, so as to throwtheimage up or down on the face of entirely from the screen.

With this apparatus the artist by drawing a picture upon the slide 5will cause said picture to be reproduced greatly enlarged upon thescreen in lines of white or colored light on a dark background, and theaudience sitting in the dark will not be able to see how it is produced,the result being very striking. The greatest freedom of movement isprovided for the artist, and, in fact, it may he said that with thisapparatus the services of an artist and not a mere copyist are necessary, the result being that any sort of a picture may be produced, notonly a line picture but ictures with brush effects and theroug y perfectin t chnioue or color effects.v The magic lantern may e placed either infront of or behind the screen, which in the latter case must be made ofthin translucent material.

the screen, as may be desired, or to cut it off Having thus described myinvention,v what I I claim as new, and desire to secure by LettersPatent of the United States, is
